Description
Technical field
The present invention relates to a kind of reclaimed rubber and preparation method thereof, be specifically related to stable reclaimed rubber of a kind of environment-friendly, high-intensity power and mooney viscosity and preparation method thereof.
Background technology
The quantity of waste old material is only second to plastic waste in spent high molecular material, and wherein learies is more than 1,000,000,000 doughnut whole world year, approximately 5000～6,000 ten thousand, China.The utilization of waste old is conducive to protection of the environment, realizes the recycling of resource, is conducive to socioeconomic Sustainable development.
Conventional regeneration glue rubber powder used is taking junked tire as main, other also comprises the raw material such as waste rubber shoe and the inner tube of a tyre, tenderizer coal tar, the oil extractum etc. of a large amount of black in regenerative process, are conventionally all added, the reclaimed rubber of preparation has very niff, larger contaminative, also contains a lot of carcinogenic chemical substances of the poisonous people of making.At present developed country has limited the rubber items such as the tire that contains these chemical substances and has used.Conventional regeneration glue need to carry out at present in regenerative process in high temperature desulfurizing tank, conventionally adds a large amount of water, needs the operations such as heated and stirred, cleaning, dehydration, refining.Its equipment and operation are more complicated, and investment is large.Current reclaiming process time of conventional regeneration glue, vapor pressure was in 1MPa left and right generally in 4h left and right, and the time is long, and efficiency is low.The physical and mechanical properties of conventional regeneration glue is poor in addition, and tensile strength is generally at 3～14MPa, but mostly at 7～8MPa.Conventionally reclaimed rubber is between the shelf lives, and 3 to 4 Mooney points that raise every day, rise to more than 180 for one month, user reflects that processing performance is special poor, and mixing pressure is not in blocks, therefore, between the reclaimed rubber shelf lives, mooney viscosity raises gradually, is the more general problem that many enterprises exist.
In view of the foregoing, conventional regeneration glue can not add in a lot of outlet rubber items, and its performance is also only applicable to low-grade rubber item, and vast outlet rubber enterprise is badly in need of environment-friendly type high intensity power and the stable reclaimed rubber of Mooney occurs.
Summary of the invention
According to above the deficiencies in the prior art, the invention provides stable reclaimed rubber of a kind of environment-friendly, high-intensity power and mooney viscosity and preparation method thereof, prepare a kind of not containing toxic substance, good mechanical property and the stable reclaimed rubber of memory property.
A kind of environment-friendly, high-intensity power of the present invention and the stable reclaimed rubber of mooney viscosity, made by following raw material reaction: waste tyre rubber powder, tenderizer Stockholm tar or rosin, reclaimed rubber activator G-680 and reclaimed rubber stablizer HXKM-8009, wherein, reclaimed rubber activator G-680 consumption is 0.3～0.6% of waste tyre rubber powder quality, reclaimed rubber stablizer HXKM-8009 consumption is 0.1～0.3% of waste tyre rubber powder quality, and tenderizer Stockholm tar or rosin consumption are 12% of waste tyre rubber powder quality.
Wherein, waste tyre rubber powder is preferably mixture that one or both arbitrary proportions in waste and old heavy load radial tire crown or waste and old crown compound of bias truck tire part mix and pulverizes and form.
The granularity of waste tyre rubber powder is preferably 40 orders.
The preparation method of the stable reclaimed rubber of a kind of environment-friendly, high-intensity power of the present invention and mooney viscosity, carries out according to following steps:
(1) waste tyre rubber powder, tenderizer Stockholm tar or rosin, reclaimed rubber activator G-680 and reclaimed rubber stablizer HXKM-8009 are mixed according to above-mentioned formula, then join desulfurization plasticizing machine and carry out desulfurization plasticizing;
(2) material of the discharge gate of desulfurization fluidizer being discharged is transferred in mill and is carried out refining, crosses roller 10 times under the roll spacing of 0.5mm;
(3) reclaimed rubber after refining is cooled to below 25 DEG C, and more than placing 24h, can obtain the stable reclaimed rubber of environment-friendly, high-intensity power and mooney viscosity.
Wherein, desulfurization plasticizing machine is preferably duct type desulfurization plasticizing machine, more preferably ZTL26-15T.The present invention adopts duct type desulfurization plasticizing machine, has nitrogen protection, than existing tank reactor high-quality, environmental protection, efficient and energy-conservation in reclaiming process process.
In the time adopting duct type desulfurization plasticizing machine, parameter setting is according to following requirement: preheating section pipe temperature is 80～130 DEG C, and the material lagging time is 5～15min, material feeding speed 0.2～0.75m/min; RS Regenerator Section pipe temperature is 130～230 DEG C, material lagging time 10～40min; Material is 5～15min in the residence time of cooling section, and the feeding speed of material is 0.2～0.75m/min.
The model of mill is preferably XK-450.
The environment-friendly, high-intensity power preparing for the present invention and the stable reclaimed rubber of mooney viscosity detect, and detect formulating of recipe, vulcanize, park, detect according to GB GB/T13460-2008 " regenerated rubber ".The reclaimed rubber that adopts formula of the present invention and method to prepare, any surface finish, color is homogeneous, tasteless.After sulfuration, the performance test results of film is: tensile strength more than 15MPa, tensile yield more than 430%, this mechanical property that has all exceeded conventional regeneration glue detects data, reclaimed rubber has only increased by 10 Mooneys and stable performance depositing after 30 days.The reclaimed rubber product that proof the inventive method prepares has been obtained breakthrough effect to the regeneration of waste old.Although cost has improved 20%, the cost ratio conventional regeneration glue of environment-friendly type high intensity power reclaimed rubber has improved 50%, has realized effective utilization of waste and old resource.
The present invention have advantage be: the stable reclaimed rubber of (1) environment-friendly, high-intensity power and mooney viscosity is compared with conventional regeneration glue, and mechanical property is improved largely, and does not contain the toxic substance containing in coal tar wet goods tenderizer conventional in traditional method; (2) adopt duct type desulfurization plasticizing machine, in reclaiming process process, adopt nitrogen protection, than existing pot type desulfurization plasticizing machine high-quality, environmental protection, efficient, energy-conservation; (3) use of new resurgent crude rubber activator makes the reclaimed rubber memory property after desulfurization stable; (4) waste and used rubber tyre is got the efficient use, this invention has outstanding economic benefit and social benefit.
